E. POSSON REFRIGERATOR CAR Nov. 30 ,1926.

E. POSSON REFRIGERATOR CAR are mounted in the end walls with their edges overlapping the belt rails and abutting against the ribs.

The inner region of the car is divided by two transverse partitions or bulkheads 50, which extend vertically between the floor and the roof, thus dividing the car into a refrigerating chamber 51, adapted to con tain perishable goods, and two refrigerant chambers 52 located adjacent the ends of the car andadapted to receive the ice inserted through the hatchwa-ys 36.

The refrigerating chamber 51 has a subfloor 53, formed by a plurality of transverse cleats 54 resting on the longitudinal frame members 55, which are supported in turn by the floor 20. Theend cleat 54 of the sub-floor is hinged at 56, for a purpose hereinafter described. Within the refrigerant chamber 52 the floor has a sheet metal covering 58, and a portion of the floor is moved to permit the depression of this sheet metal plate to form a transverse drain channel 59, having a drain trap connected thereto and leading through the floor of the car adjacent each side wall, as shown in r igs. 2 and 3. These drain traps may be of the form described and claimed in my prior Patent No. 1,329,015, granted January 27, The sheet metal covering 58 of the ice chamber floor is extended upwardly at the side wallsof the car, as shown at 61, in contact with the inside sheathing, and a similar sheet metal plate 62 is extended upwardly in contact with the inside sheathing 41 and the end wall of the car, thus forming a waterproof lining for the sides and end walls of the ice chamber. A plurality of vertical cleats 63 are secured to the end wall 38 in contact with the inner sheet metal lining 62, and a reticulated sheet metal plate 64 is secured to these cleats, thus forming a plurality of channels 65, through which the air can circulate around the ice in the refri 'erant chamber.

i plurality of brackets 66, which may preferably be malleable castings, are secured to the floor and arranged to straddle the drain channel 59, shownin Fig. 3. These brackets have the form illustrated particularly in Fig. 6, each comprising a lower base flange 66, having a vertical flange 66 extending upwardly from the middle portion thereof and a transverse flange 66 extending outwardly in opposite directions from the middle portion of the vertical flange and uniting it with the base flange. A horizontal flange 66 extends longitudinally from the transverse flanges 66 and is formed integrally with the upper edge of one portion of the vertical flange 66*. One end of the base flange 66 is offset downwardly, as shown at 66, and these offset portions are united to the floor by bolts 6? passin through the apertures 68. The other end or the base flange and the opposite end of the vertical flange 66" are formed integrally with the angular flange 66 which is adapted to engage and overlap the opposite edge of the drain channel, as shown in Fig. 3. These brackets are adapted to support the bulk head 50, which comprises a plurality of vertical posts 70 which rest at their lower ends on the base flanges 66" of the brackets and seat against the vertical flanges 66, being slotted to receive the vertical flange 66". These posts are secured to the flanges 66 by bolts 71 and to the flanges 66 by transversely extending bolts 72. All of the posts re further united by a transverse bar 73, which rests on the flanges 06 and is secured to the posts by bolts 74. At their upper ends the posts 70 are secured by bolts 75 to brackets 7 6. These brackets are connected by bolts 77 to the roof boards and to a transverse frame member 78 which extends between the side plates 22.

The surface of the partition or bulkhead 50 toward the ice chamber 52 is formed by a reticulated sheet metal plate 80, which is secured to the posts 70 by a plurality of bolts 81, these bolts passing also through metal cleats 82, which extend vertically in contact with the outer surfaces of the plate 80, as shown particularly in Fig. 2. The opposite sides of the post which are directed toward the refrigerating chamber 51 have the partition boards 83 secured thereto, and a plurality of layers of heat-insulating material 85 are mounted in contact with the boards 83 between the posts 70. Other retaining boards 86 seat against the inner sur' faces of the layers of insulating material, and these boards are helt in position by plates 87 which are secured to the latteral sides of the posts 70. A galvanized sheet metal plate 88 is secured over the inner exposed surfaces of the posts 70, plates 87, and boards 86, thus forming a waterproof lining for the surface of the bulkhead which is directed toward the ice chamber. A plurality of vertical air channels 89 are thus formed between the reticulated sheet metal plate 80 and the sheet metal plate 88, through which the air may circulate in proximity to the ice. The partition boards 83 and 86 and the associated water proof and heat-insulating construction terminate below the ceiling of the car, and a reticulated sheet metal plate or woven wire screen 90 is mounted be tween the upper edges of the partition boards and the ceiling boards, thus permitting the warm air from the upper part of the refrigerating chamber to pass through the upper part of the bulkhead into the ice chamber and into the vertical air channels around the ice chamber. The partition boards 83 and 86 also terminate above the floor of the car, a single transverse cleat 91 being secured to the posts 70 below the lower mosaics edges of ithe iboxards 83, :thus :forming ropenings 1-9.2 on zopposite sides of :the .cleats 191 through which :the cold air from ithe lower p artiiof itlle ice chamber i may 1 pass outwardly into the refrigerating chamber. This open construction in the lower part-oi the bulkhead alsoipcrmits:access to the drainchannel 5 9 for the purpose of cleaning the same, and the facilityof cleaningthis:channel is increased Eby athe Ihinged mounting of the board .54 of the :sub-floor, which .may be movediupwardly out of its.normal'position.

,A bar 93, similarito theibar=73,.is.-secured to the end wall of the car in contact with the Wertical ribs'6i3'by bolts194. Thislbar is adapted to rest upon a:pluralityiofibrachets 95, eachof which Eis tlocated Lin alinement with i one .of :the "brackets 66. Each of .these brackets illilS a horizontal upper flange 95 locatediin substantially the: same 1 plane with the horizontal rliia-nges 66 of the brackets 66 and with the-upper surface oftthe sub-'fioor 5 1. A series of T-bars 96, each havinga verticalrstem 9.6 and horizontal :flanges196", are {supported 'hyithebrackets 66Ltlll-d 95, the horizontal-flanges QO EOfIthG 1T bai-sbeing curedztottheihorizontal"flanges 66 and 9510f the zbraclrets :by :means of rivets 97. At ithe sides of the ice rchamberiangleIbars198 .are securedito the inside sheathing S24 and .to the vertical cleats :located 'within the :inside sheathing {of the :ear by :means i of bolts 199. Theihorizontahfianges 96 ofthe 1T hers and the rhorizontal vftanges of :the angle bars 1 98 are adapted to form supports:foraplurality of removable jS LIbTflOQI' sections .100, which form-the ice platform within the refrigerantchaniber. sEach:platformsection is:made up of .axpluralityof grate bars 101, each of which is: similariin 'GOIltOUTCtOitllQ stationary bars 78 and L93 which are secured 'to the bulkhead and to :the end wall, respectively. These grate ibarssare spaced ap artibyras series of collars 1102, and are united by longitudinal, bolts 1103 which extend th rouglu the grate bars and through thecollars, asshownparticularly in Fig.5. When the platform ssectionsxare placed inpiositiongonnfiheflanges of the Tebars and angle bars,:their;upper edges lie in the same plane with-theiupperredges of the stationary bars '73 .and :93, :and the end bars ;101 of the platform sections are spaced from i these stationary :bars by blocks 104, which are; securedthereto 'by bolts 105.

The ice platform oflthe refrigerant. chamher is thus made-up ofaaplurality'oi'removable. sections which are :located in proximity to the .tioor proper, designated by numeral 20,: the brackets 66 and 9.5 havinga comparatively sm-all depth yertically, so that this construction is adapted to increase the capacity of the; ice chamberby several hundred pounds as i compared with the refrigerating cars heretofore iuscd. This :capacity {is :Eurthcr increased by placing in ZWHtGIPl'OOf ;gal-
